hi,

That user has Laptop...
1.Operating System is WinXp
2.Browser : IE 6.0 , Opera (at first user had,But we asked to uninstall that.)
3.Antivirus : EScan
4.Internet Connection : BSNL Broadband 750 UL Plan


One information.... ..usally if the user has Mozilla firefox as Web browser.it will not work.. we always to uninstall the mozilla firefox.

We had asked the user the reinstall the OS...
And then we tested our software the file movement is not worked.

At first she had the Vista as OS and we have some other issues in her system... so we had ask her to change OS to WinXp

She has installed the WinXp OS as pirated version...

With Regards,

Mani
